Definitions

  • the present invention relates to a system for verifying the connection of ends of electrical conductors in the corresponding terminals of a connector, as well as an automatic connection installation comprising said system.
  • a connector has a plurality of terminals each consisting of a bore passing right through the connector, the end of the connector to be connected being introduced through the rear face of the connector. For the connection to be correct, it is necessary that the end of the conductor is plugged into the appropriate terminal and that the end of the conductor is fully inserted into said terminal.
  • the operator can be helped, in this verification, by directing a point light beam so that it crosses the terminal in which a determined conductor must be inserted.
  • a sighting provides only information of the "all or nothing" type, which makes it possible to determine that one end of the determined conductor is plugged into the appropriate terminal, but not that the connection is correct, that is that is, as already indicated, that the end of the conductor is fully inserted into said terminal.
  • the object of the present invention is to avoid these drawbacks and it relates to a system making it possible not only to determine that the end of a particular conductor is introduced into the terminal which corresponds to the latter, but also to verify that the positioning of said said end is correct, in other words it is fully inserted "fully” into said terminal. This avoids the disadvantages of prior systems operating by "all or nothing".
  • the system for checking the connection of the first ends of electrical conductors in the corresponding terminals of a connector having a rear face for introducing said ends of the conductors and a front face, each of said terminals being constituted a bore passing right through the connector is characterized in that it comprises first lighting means intended to obliquely illuminate the front face of said connector, said first lighting means having the shape of a ring or crown, the inner illumination face of which is inclined, being oriented towards the front face of the connector in the position mounted thereon, and electronic means for observing and displaying said front face, so that the variations in contrast on said front face of the connector makes it possible to determine that a particular conductor end is introduced into the bor appropriate connector and that the positioning of said conductor end is correct.
  • patent EP-A-0194104 describes an apparatus for the automatic inspection of electrical connection pins, with the aim of rejecting the connectors. with defective pins.
  • the connector is placed under a television camera connected to an analysis circuit which decomposes the image supplied by the camera and compares it with predetermined tolerances.
  • document US-A-4 162 126 describes an apparatus for highlighting surface defects on an object, comprising illumination means for illuminating the surface from two symmetrical directions, and a sensor comprising a camera television or the like to detect the light reflected from the surface of the object, thereby analyzing the defect.
  • said observation means comprise a CCD camera (charge coupled diodes).
  • the present invention also relates to an automatic installation for connecting the first ends of electrical conductors in the corresponding terminals of a connector, comprising a computer control device, remarkable in that it comprises a system for checking the connection of said first ends such as defined above, controlled by said computer device.
  • it comprises mechanical means for maintaining and recognizing said connector.
  • said mechanical holding and recognition means may comprise several centering pins capable of moving radially relative to said connector, at least one of said centering pins being intended to cooperate with an indexing member, of corresponding shape, provided on said connector.
  • each of said centering pins is mounted at the free end of an arm, the other end of which is connected to a helical ramp provided on a support that can rotate.
  • the installation may include second point lighting means capable of moving according to a coordinate system Ox, Oy parallel to the front face of the connector so as to illuminate a predetermined terminal of the latter .
  • the installation comprises a barcode reader for identifying the electrical conductors, and / or a plurality of housings for grouping the second ends of the electrical conductors.
  • Figure 1 is a schematic perspective view of the automatic connection installation of the invention comprising the connection verification system of the invention.
  • FIG. 2 is a side view in partial section, on a larger scale, of part of the installation of FIG. 1.
  • Figure 3 is a schematic top view of the mechanical means for holding and recognizing the connector, belonging to the installation of the invention.
  • FIGS. 4a and 4b show how a connector can be held in position using the holding means of FIG. 4.
  • FIG. 5 schematically shows the connections of the control microcomputer to the various elements of the installation of the invention.
  • FIG. 6 illustrates the implementation of the oblique lighting means and observation means of the installation of the invention.
  • Figure 7 is a detail of a display screen.
  • the installation 1 of the invention comprises mechanical means for holding and recognizing 2 of a connector 3 (round in this example) described in detail below.
  • the connector 3 comprises a plurality of terminals 4, each for the connection of the end 5 of an electrical conductor 6 introduced by the rear face 3a of the connector 3.
  • An optical fiber 7, mounted on a table 8 for controlling the movement of the latter according to an orthogonal coordinate system Ox, Oy, can move parallel to the front face 3b of the connector 3, so as to illuminate a terminal 4 chosen in which must be introduced the end 5 of the appropriate conductor 6 ( Figure 2).
  • oblique lighting means 9 are provided on the front face 3b of the connector 3. These means 9 have the shape of a ring or ring coaxial with the central axis 10 of the connector 3 in position in the installation 1 , the lighting face 9a of the ring 9, inside the latter, being inclined in the direction of the front face 3b of the connector 3.
  • the optical fiber 7 and the ring 9 are connected, by the respective links 11 and 12, to a light generator 13 with variable intensity.
  • electronic means 14 for observation and display thereof are also provided, such as for example a CCD camera (charge coupled diodes).
  • CCD camera charge coupled diodes
  • the installation 1 further comprises a bar code reader 16 making it possible to read the code 6a of a particular conductor 6, and a plurality of housings 17 of the conductor, identified by light-emitting diodes 17a, making it possible to group the ends, not connected to the connector 3 of the conductors 6, having the same destination.
  • the mechanical means 2 for holding and recognizing a connector comprise, in the case of a round connector, an annular support 20 capable of being driven in rotation about its axis 27 by a stepping motor 21.
  • the support 20 comprises, on its upper face, helical ramps 22 (three in the case shown) for radially move (as shown by the double arrows 23) an indexing pin 24 and two centering pins 25 of the connector, each carried at the free end of an arm 26, the other end of which is connected to the corresponding ramp 22 .
  • the indexing pin 24 and the centering pins 25 can be arranged internally at the connector 3 (FIG. 4a), the indexing pin 24 then cooperating with a hollow member 30a of corresponding shape formed internally at the connector 3, or l the indexing lug 24 and the centering pins 25 may be disposed externally at the connector 3 (FIG. 4b), the indexing lug 24 then cooperating with a projecting member 30b of corresponding shape provided externally at the connector 3.
  • the installation 1 of the present invention is implemented as follows.
  • the connector 3 is put in place thanks to the mechanical means 2 for holding and recognizing.
  • the microcomputer 15 controls the stepping motor 21 so as to rotate the support 20 and, thus, thanks to the helical ramps 22, to radially move the lug of indexing 24 and the centering pins 25, in a controlled manner, by adapting the position of the lug 24 and the pins 25 to the particular diameter of the connector.
  • the connector 3 is, therefore, securely held in position, in an indexed manner, and, moreover, these means 2 also play a role in recognizing the connector 3, in that the lug 24 and the pins 25 "measure” , so to speak, the diameter of the connector.
  • each electrical conductor 6 can be identified by reading its barcode using the reader 16 connected to the microcomputer 15. The latter can then control the movement of the optical fiber 7 on the table 8, so that the light beam 7a originating therefrom designates the terminal 4 of the connector 3 in which the end 5 of the conductor 6 which has just been identified must be inserted, preferably using a tool specific.
  • the end 5 is plugged in by the rear face 3a of the connector 3, opposite the front face 3b opposite the optical fiber 7.
  • the unconnected ends of the conductors 6 can be grouped, according to their destination, in the housings 17 identified, each by a light-emitting diode 17a, the diodes being controlled by the microcomputer 15.
